獲取 TypeCaste 運行時錯誤：無法將 ILogger< WorkletSelectionForm> 轉換為 ILogger< MainForm>
uj5u.com熱心網友回復：
您可能還需要將 注入ILogger<MainForm>建構式，這些型別和實體不可互換。
試試這個
public class WorkletSelectionForm : Form
{
private readonly ILogger _logger;
private readonly ILogger<MainForm> _mainFormLogger;
public WorkletSelectionForm(
ILogger<WorkletSelectionForm> logger,
ILogger<MainForm> mainFormLogger)
{
_logger = logger;
_mainFormLogger = mainFormLogger;
}
private void btnClick_click(object sender, System.EventArgs e)
{
MainForm _frm = new MainForm(_mainFormLogger);
}
}
